Conditional deletion of Sall1 in dorsal PCs indicates that Sall1 regulates PC fate progression. Sall1 (red) expression is localized to the ventral telencephalon and does not extend into the dorsal cortex in Sall1-cKOEmx1 animals (arrow, B), unlike controls (A) at E12.5. Tuj1 staining (green) of cortical neurons at E12.5 identified an increase in preplate cell number in Sall1-cKOEmx1 (D) animals compared with controls (C). CSPG (red) immunostaining of the subplate and marginal zone identified an increase in these structures in Sall1-cKOEmx1 (F) animals compared with controls (E) at E18.5. Tbr2 (red) immunostaining at E18.5 identified an increase in IPCs in Sall1-cKOEmx1 (H) animals compared with controls (G). PC, progenitor population; PP, preplate; SP, subplate; CP, cortical plate; MZ, marginal zone. Scale bar: 100 μm (C,D,G,H); 350 μm (E,F); 400 μm (A,B).
